elp Normal ▾ B IU A - Corn Breeding / Genetic Problem A corn breeder is working with 2 inbred corn plants. He is interested in two traits: High yield (produces lots of corn) and drought tolerance (does not need lots of water). High yield (H) is dominant to low yields (h). Drought tolerance (D) is dominant to drought intolerance (d). M BEE Inbred 1 is true breeding for drought tolerance and low yield (DDhh). Inbred 2 is true breeding for drought intolerance and high yield (ddHH). In the parent cross (P) the corn breeder crossed inbred 1 with inbred 2. The resulting F₁hybrid (DdHh) was heterozygous for drought tolerance and high yields. Phenotypically all the corn needs little water to grow and produces lots of corn. This is the corn that is sold to farmers, planted in the Spring and harvested in the Fall. Explain why the farmer does NOT hold back some of the Fall harvested (F₂) kernels and plant them next Spring. You must show your work. (Hint: As a %, how many of the F2 kernels still…

true or false (please do them ALL) 1. Heritability estimates is a portion of phenotypic variation contributed by heredity. Traits in pigs such as ovulation rate and number of piglets produced per year are highly heritable traits. 2. The formula for computing crude protein is equal to the amount of nitrogen multiplied by 6.25. This is based on the fact that ALL protein materials contain 16% nitrogen.  3. Essentiality of a nutrient depends on the factors such as species, age, health, metabolism.  4.The deficiency symptoms of Selenium may be associated or similar with vitamin E deficiency.  5. Lipids have similar elemental components as carbohydrates but contains more energy because that ratio is greater for oxygen

NAME: Patterns of Inheritance Worksheet 1. True Breeding Parental Cross A homozygous dominant purple flowered plant is crossed with a homozygous recessive white flowered plant. a. What are the genotypes of the parent plants? (Use the Punnett square to determine the outcomes of this cross. Remember to place the gametes along the left side and top of the square. (P=Purple, p=white) b. What is the genotype of all F₁ plants? 1 b. c. What is the phenotype of all F₁ plants? C. d. How many plants out of 4 will produce white flowers? d. a. 2. Monohybrid Cross: The F₁ offspring from the above problem are allowed to self fertilize. a. What are the genotypes of the F₁ parents? a. (Use the Punnett square to determine the outcomes of this cross. Remember to place the gametes along the left side and top of the square.) b. What is the genotype ratio for this cross? c. What is the phenotype ratio for this cross? d. How many plants out of 4 will produces white flowers? d. b. C.

Help me

please help with question H!

please help me with the following question asap please its important!!   State your null hypothesis for the flower experiment, giving the probability of a left-handed flower    # and probability of a right-handed flower (assuming right-handed is dominant) and what is the alternative hypothesis?   Null hypothesis :  Alternative hypothesis:
